Who runs DNS and the edge for America's biggest tech companies

Hostname by hostname, we find which authoritative DNS service answers for the 10 largest US tech companies (the FTEC top 10): their main sites, logins, stores, developer portals, downloads and brand domains. Then which hyperscalers (AWS, Azure, Google Cloud) and edge providers (Akamai, Cloudflare, Fastly, F5, Vercel) serve them. Re-scanned every week. The rest of the Fortune 500 is next.

Share of the authoritative DNS behind every live public hostname, weighted by how much traffic the hostname is likely to carry (primary site and critical login, store, API and support names count most). A zone served by several vendors is split by nameserver count. "Self-hosted" = nameservers on the company's own network. Full DNS rankings and comparison →
